5A High-Temperature Resistant Smart Home Appliance Micro Switch

The HK-04G-L switch fully adheres to Yueqing Tongda's "Three-Layer Quality Control System": Raw material stage. Each batch of silver-tin alloy contacts must undergo spectral component testing, and the casing must pass a 72-hour aging resistance test. Production stage, Relying on fully automated assembly lines, precise component fitting is achieved, with dimensional errors controlled within 0.02mm. Finished product stage: 100% of products undergo push-button lifespan testing, high and low-temperature cycling tests (-40°C to 85°C), and insulation resistance testing (≥100MΩ), maintaining a 100% factory pass rate.At the same time, the product enjoys a unified one-year warranty service from the company. If non-human-caused faults occur during use, customers can receive free replacement and technical support. Currently, the HK-04G-L switch has an annual sales volume of over 200,000 units. In addition to the domestic market, it is also exported to Europe and Southeast Asia with UL and VDE certifications, becoming a representative model of Yueqing Tongda's standardized products that combines both reputation and market competitiveness.Whether for basic circuit control requirements or mild customization scenarios, the HK-04G-L switch, with "stable performance and flexible adaptation" as its core, demonstrates Yueqing Tongda's technical strength in switch manufacturing and provides reliable circuit control support for equipment across various industries.

Suitable for automotive electronic status monitoring.

Vehicle charging port: when inserting the charger, push the swing arm to connect the charging circuit, with silver alloy contacts compatible with a 12V/10A vehicle power supply; 

Seat adjustment: the limit switch at the end of the slide rail detects the seat's extreme positions through the swing arm, preventing motor overload.
